For good rankings in search engines, is it better to have a plain text header with your title? Like <h1>Title</h1>?

I've heard rankings depend on what's in your h1, h2, h3 tags. It seems like most sites have an image logo instead. Is this just as good?

Thanks for your help.

I suggest you use <h1>Talk Freelance</h1>, It gives more emphasis on google spiders. you can have the images optimized in alt tags. H1, H2 and H3 is like meta tags that needs to put the keywords on it.
